I've tried searching here and Google, but I'm having no luck. My driveway is a sight slope. When there is snow on it I'm having issues. If my Jeep is backed into the garage and I can drive down it no problem. However, if I back down it I can't brake. Pressing the brakes causes the Jeep to start sliding, all the way into the road. It honestly doesn't feel like it has the best brakes, but I'm not sure how they should feel in a 17 year old Jeep with oversized tires. I blew a rear wheel cylinder over the summer so I replaced both sides. Twisting off the steel brake line on both sides, so I replaced those a well with factory lines from the dealer. While I was doing this I also replaced the rubber line that drops down to the axle, thinking maybe it was old and starting to rot and clog up. Bled the system until I started getting clean brake fluid out of both when cylinders. No improvement in braking though. And I just slid down my driveway again. Looking out my window, the fronts are locked up and the back wheels are turning. I'm pulling my hair out on this one.
Rear brake issue

Simple problem, simple lack of understanding as to how brakes work. Brakes are designed to function best with the vehicle going forward. They are biased heavily to the front in both line pressure and sheer physical size of components since that is the safest way to stop from killing folks.
Now you are expecting them to work the same going backwards and that is never gonna happen. The easy answer is to just tie the front and rear brakes together via the transfer case and pop that into 4 hi as soon as you fire it up before you hit reverse. Makes all the difference in the world.
I do understand that the brakes work best going forward. My confusion is that the back doesn't lock even though the front do on the slippery surface. I will definitely try the 4 hi next time, thanks for that tip
Alright, since you are going backwards, the brake function has to reverse. It can't so now the weight is on the rear brakes and over powering them since they are not designed to be front brakes. The front brakes are locking up because the weight is heavily biased onto the rear brakes through both angle and direction of travel. They will do the exact same thing if you get out in a safe place, reverse at a high rate of speed and slam on the brakes. The fronts will lock and skid, the backs will keep turning. You are just duplicating that in slow motion.I do understand that the brakes work best going forward. My confusion is that the back doesn't lock even though the front do on the slippery surface.
